Book Synopsis Mineralization and Sustainable Development in the West African Craton by : T. Aïfa
Download or read book Mineralization and Sustainable Development in the West African Craton written by T. Aïfa. This book was released on 2021-07-22. Available in PDF, EPUB and Kindle. Book excerpt: This Special Publication combines results obtained by interdisciplinary groups from numerous academic institutions working on Paleoproterozoic formations to decipher the origins of the main mineralization resources in the West African Craton (WAC) and their impacts on African economic development. Structural, geophysical, sedimentological, stratigraphical, geochemical, petrophysical and mineralogical analyses have been used to highlight the complexities involved in mineralization emplacement and its origin and evolution within the WAC. Fourteen articles contribute to new knowledge in mineral research. They show that the geodynamic evolution of the WAC is complex from one area to another: it involves subduction, collision and obduction during several deformation phases ranging from Birimian (2.3–2.0 Ga) to Pan-African (650–450 Ma) events. Various modelling techniques, when integrated, help in understanding the mechanisms of mineralization emplacement, some of which are still a matter of debate. The challenge for further studies is mitigation for sustainable development that can be appropriately used to minimize such damage.

Book Synopsis Continental Evolution: The Geology of Morocco by : André Michard
Download or read book Continental Evolution: The Geology of Morocco written by André Michard. This book was released on 2008-09-26. Available in PDF, EPUB and Kindle. Book excerpt: Morocco is one of the most fascinating lands in the world from the point of view of its geological structure and evolution. Our knowledge on the geology of the country has been greatly improved during the last decades, based on numerous seismic profiles and boreholes, seismological analysis of focal mechanisms, seismic tomography, gravimetric/geodetic modelling and, on the other hand, based on a big National Program of Geological Mapping including modern geochemical analyses (trace elements) and reliable isotopic datings (39Ar-40Ar, U-Pb zircon, Sm-Nd, etc). Moreover, a number of academic studies have been performed in relation with the increasing number of Moroccan universities. Accordingly, there was an utmost urgency to undertake a new treatise of Moroccan geology which could substitute for the classical Eléments de géologie marocaine, published in 1976 by A. Michard in the Notes et Mémoires du Service géologique du Maroc (re-edited twice since 1976, with more than 6000 copies sold, and... translated in Japanese for engineers!). A new treatise has been prepared between April 2006 and July 2007 under the coordination of A. Michard, assisted by O. Saddiqi, and A. Chalouan, by a wide panel of authors from Morocco, France or Belgium among the best connoisseurs of the country. In order to emphasize the general interest of the book, we finally retain the following title: Continental Evolution: The Geology of Morocco. Structure, Stratigraphy, and Tectonics of the Africa-Atlantic-Mediterranean Triple junction. The editing and production of this book was supported by the following organisations: The Geological Society of France (SGF) The National Office of Hydrocarbons and Mines of Morocco (ONHYM) The International Lithosphere Program (ILP)

Book Synopsis Natural Hazards in West and Central Africa by : Samuel J. Freeth
Download or read book Natural Hazards in West and Central Africa written by Samuel J. Freeth. This book was released on 2013-03-09. Available in PDF, EPUB and Kindle. Book excerpt: Attention to the problems posed by natural hazards in West and Central Africa was brought into sharp focus by the deaths of an estimated 1700 people in the valleys to the north of Lake Nyos in 1986. Prior to that the only, well documented, major natural catastrophe was the 1983 earthquake which killed at least 275 people in northwestern Guinea. Though we would not wish to appear to suggest that the 1939 Accra earthquake, which killed 16 people, or the Lake Monoun disaster, which killed 37 people in 1984, were not significant events for the areas concerned. The full horror of the Lake Nyos gas disaster was exacerbated, as far as the outside world was concerned, by initial uncertainty concerning its cause. During the first phase of the investigation there were considerable disagreements between some of the participating groups of scientists. Many of these disagreements have now been resolved and it is to be hoped that the contributions in this volume will further help to resolve some of the outstanding uncertainties. However, although it is important to understand what happened at Lake Nyos in 1986, and why it happened, it is more important for the future of that area that further similar disasters should be avoided. We can only hope that this volume will help to establish a solid foundation for future research into ways of removing excess gas from the lake.
